Operation Manual – NTPH3C S5600 Series Ethernet Switches-Release 1510 Chapter 1 NTP Configuration1-20The above configuration configures S5600-1 and S5600-2 to listen to multicast packetsthrough their VLAN interface 2, and H3C3 to advertise multicast packets through VLANinterface 2. Because S5600-2 does not reside in the same network segment with H3C3,S5600-2 cannot receive multicast packets sent by H3C3, while S5600-1 issynchronized to H3C3 after receiving multicast packets sent by H3C3.View the status of S5600-1 after the synchronization.[S5600-1] display ntp-service statusClock status: synchronizedClock stratum: 3Reference clock ID: 3.0.1.31Nominal frequency: 60.0002 HzActual frequency: 60.0002 HzClock precision: 2^18Clock offset: 0.0000 msRoot delay: 16.19 msRoot dispersion: 18.18 msPeer dispersion: 10.94 msReference time: 08:12:05.430 UTC Apr 25 2006(C7F85855.6E4302B4)The output information indicates that S5600-1 is synchronized to H3C3, with the clockstratum being 3, one stratum higher than H3C3.# View the information about the NTP sessions of S5600-1 and you can see that aconnection is established between S5600-1 and H3C3.[H3C4] display ntp-service sessionssource reference stra reach poll now offset delay disper*************************************************************************[1234] 3.0.1.31 127.127.1.0 2 1 64 2 -11.0 0.0 0.8note: 1 source(master),2 source(peer),3 selected,4 candidate,5 configured1.7.5 NTP Server Mode with Authentication ConfigurationI. Network requirementsThe local clock of H3C1 operates as the master NTP clock, with the clock stratum set to2.An S5600 series switch operates in client mode with H3C1 as the time server. H3C1operates in the server mode automatically. Meanwhile, NTP authentication is enabledon both sides.
